Abstract

A wasted carpet and felt scrap recycling apparatus is provided. The waste carpet and felt scrap recycling apparatus includes a feeding unit that feeds a cut scrap while forming a feeding path and a supply unit that is connected to the feeding path and supplies the scrap that passed the feeding unit along the feeding path while pressing the scrap. A separation unit is spaced apart from the supply unit, and provides a frictional force to one surface of the scrap supplied from the supply unit through rotation of the supply unit and separates the scrap into fiber and recycled material.

First claim

What is claimed is:

1. A waste carpet and felt scrap recycling apparatus, comprising:
a feeding unit configured to feed a cut scrap while forming a feeding path;
a supply unit including a supply roller connected to the feeding path and configured to supply the scrap that passes the feeding unit along the feeding path and press the scrap; and
a separation unit spaced apart from the supply unit, and configured to provide a frictional force to one surface of the scrap supplied from the supply unit through rotation of the supply roller of the supply unit and separate the scrap into fiber and resin,
wherein the separation unit includes: a rotary body coupled to a rotary shaft and rotated in one direction; and a plurality of saw-tooth wires disposed on an exterior peripheral surface of the rotary body, for raking one surface of the scrap to separate the scrap into fiber and resin when the rotary body is rotated,
wherein the saw-tooth wires are installed on the exterior peripheral surface of the rotary body at an installation angle of about 40 to 90 degrees relative to the exterior peripheral surface of the rotary body, and
when the installation angle and a number of the saw-tooth wires are increased, then the scrap is produced with thinner fiber, and when the installation angle and the number of the saw-tooth wires are decreased, then the scrap is produced with thicker fiber.

2. The waste carpet and felt scrap recycling apparatus of claim 1 , wherein the supply unit includes:
a plate that supports a lower portion of the scrap; and
a supply roller disposed at an upper portion of the scrap, and configured to supply the scrap to the separation unit while pressing the scrap and rotating in the same direction as that of the rotary body.

3. The waste carpet and felt scrap recycling apparatus of claim 2 , wherein the supply roller is rotated at a speed less than the rotational speed of the rotary body.

4. The waste carpet and felt scrap recycling apparatus of claim 1 , wherein a spacing interval between the separation unit and the supply unit is adjusted.

5. The waste carpet and felt scrap recycling apparatus of claim 1 , further comprising a plurality of feeding units, a plurality of supply units, and a plurality of separation units.

6. The waste carpet and felt scrap recycling apparatus of claim 1 , wherein one to eight saw-tooth wires are installed per inch on the exterior peripheral surface of the rotary body.
